The associated NCEI study type is Tree Ring. The data include parameters of tree ring with a geographic location of Alberta, Canada. The time period coverage is from 23 to -67 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data. Tree ring data from the International Tree Ring Data Bank and World Data Center for Paleoclimatology archives. Most data sets include raw treering measurements (most are annual ring width, with some collections of earlywood or latewood width or wood density), plus chronologies (standardized growth indices for a site compiled from multiple treering samples). Reconstructions of climate variables are included with some of these data sets. Each data type is stored in a separate data file; the data type is coded into the file name.

The naming format for each species' cores is as follows: Picea glauca (GLP01A), Betula papyrifera (GLB01A), Pinus banksiana (GLJ01A), Populus tremuloides (GLA01A). NOAA Template Raw Measurements file added 2019-08-22. ABSTRACT SUPPLIED BY ORIGINATOR: Variation in tree recruitment, mortality, and growth can alter forest community composition and structure. Because tree recruitment and mortality events are generally infrequent, long-time scales are needed to confirm trends in forests. We performed a 50-yr demographic census of a forest plot located on the southern edge of the Canadian boreal forest, a region currently experiencing forest die-back in response to direct and indirect effects of recent severe droughts. Here, we show that over the last 30 yr biomass, basal area, growth, and recruitment have decreased along with a precipitous rise in mortality across the dominant tree species. The stand experienced periods of drought in combination with multiple outbreaks of forest tent caterpillar (Malacosoma disstria) and bark beetles. These insect disturbances interacted to increase mortality rates within the stand and decrease stand density. The interaction of endogenous and exogenous factors may shift forests in this region onto novel successional trajectories with the possibility of changes in regional vegetation type.
